Figure 1

Box-plot representing net photosynthetic rate (μmol CO₂ m⁻² s⁻¹) for genotype AP-947, AP-1005, AP-1006, AP-2278, AP-2298 and AP-2300. Well watered samples (filled); water-deficit-treated samples (empty) (n = 3 per treatment per genotype). The midline of the box represents the median value for photosynthesis, the upper and lower bounds of the box represent the interquartile range, and the whiskers extend to the most extreme values that are not outliers.
